Abstract Millimeter-wave communications are suitable for application to massive multiple-input multiple-output systems in order to satisfy the ever-growing
data traffic demands of the next-generation wireless communication. However,
their practical deployment is hindered by the high cost of complex hardware, such
as radio frequency (RF) chains. To this end, operation in the beamspace domain,
through beam selection, is a viable solution. Generally, the conventional beam
selection schemes focus on the feedback and exhaustive search techniques. In
addition, since the same beam in the beamspace may be assigned to a different
user, conventional beam selection schemes suffer serious multi-user interference.
